There is Form Code:

Private Sub _TMR2_Tick() Handles TMR2.Tick
If Browser.DocumentText <> Nothing Then
If _StringNumber(Browser.DocumentText, Word) > 0 Then
If _IsThere = False Then
MsgBox("Online!", MsgBoxStyle.Exclamation, "Online!")
_IsThere = True
End If
Else
_IsThere = False
End If
TMR2.Stop()
End If
End Sub
